You don't mention which system you are using. TeXLive is organized in quite a different way from MikTeX. With MacTeX, take a look at

http://email.esm.psu.edu/pipermail/macosx-tex/2007-September/032106.html

and for MikTeX, there's a brief explanation at

http://pp3.sourceforge.net/manual/Increase-TeX-s-memory.html

Another option is to use gnuplot to generate the curves, adding the axis and labels with pstricks. The gnuplot file would look something like

set terminal postscript eps size 9cm,9cm
unset title
unset border
unset xtics
unset ytics
unset key
set lmargin 0
set rmargin 0
set tmargin 0
set bmargin 0
set output '~/Documents/texfiles/bs.eps';
plot [ ] [-12:4] '~/Documents/texfiles/bs_p21a_8.dat' using 1:2 with l; #plot column 2 against column 1
#need one line like the above for each curve, with new column index in place of 2

Then, in your psgraph code, replace all the listplot lines with

\rput[bl](0,-12){\includegraphics{bs}}
